1) Sink the valve deeper, but that lowers compression
2) mill the spring seat down
I need around .100 on intake and .140 more on exh, thoughts?
Oh, and the reason i need more height is because my spring pressures are too high. (70-80# too high)
Or am i looking at it wrong???
Not too proud to admit i dont know much!

Good morning Jim and to all,
The ideas you have listed will work. You can also find out if your favorite intake or exhaust valve manufacture has valves that are plus .050 and or .100 longer. Then use different assembly height keepers and / or retainers to get to your final height requirement. Have you contacted you valve spring Manufacturer to see if there is some other number valve spring that can accommodate the pressure's you're looking for?
Then you won't have to perform any additional machining processes.
Just a couple of suggestions that might help you, Have a Good Day.
